Researchers used satellite data from 2003 to 2011 to examine surface
temperatures across as wide swath of west Texas, which has built four of
the world's largest wind farms. The data showed a direct correlation
between night-time temperatures increases of 0.72 degrees C (1.3 degrees
F) and the placement of the farms.

As in the orchards, the cool air next to the ground is mixed by the blades with warmer air above.

Will this "put a damper on efforts to expand wind energy as a green energy solution"?

At first, I thought no, because it is just a local phenomenon. But in the overheated (sorry) debates on energy policy, expect to see this finding dragged in.
